Résumé : International audience
This study aims to describe current risk management practices and policies across the world in relation to personal exposures from devices emitting radiofrequency fields, environmental exposures from fixed installations and exposures in the work environment. Data from 86 countries representing all WHO regions were collected through a survey. The majority of countries (76.8 %) had set exposure limits for mobile devices, almost all (90.7 %) had set public exposure limits for fixed installations and 76.5 % had specified exposure limits for personnel in occupational settings. A number of other policies had been implemented at the national level, ranging from information provisions on how to reduce personal exposures and restrictions of usage for certain populations, such as children or pregnant women to prevention of access around base stations. This study suggests that countries with higher mobile subscriptions tend to have set radiofrequency exposure limits for mobile devices and to have provisions on exposure measurements about fixed installations.

Résumé : International audience
Whilst it used to affect mostly intravenous drug users and patients who underwent valvular surgery with suboptimal infection control procedures, fungal endocarditis is now mostly observed in patients with severe immunodeficiency (onco-haematology), in association with chronic central venous access and broad-spectrum antibiotic use. The incidence of fungal endocarditis has probably decreased in most developed countries with access to harm-reduction policies (i.e. needle exchange programmes) and with improved infection control procedures during cardiac surgery. Use of specific blood culture bottles for diagnosis of fungal endocarditis has decreased due to optimisation of media and automated culture systems. Meanwhile, the advent of rapid techniques, including fungal antigen detection (galactomannan, mannan/anti-mannan antibodies and β-1,3-d-glucans) and PCR (e.g. universal fungal PCR targeting 18S rRNA genes), shall improve sensitivity and reduce diagnostics delays, although limited data are available on their use for the diagnosis of fungal endocarditis. New antifungal agents available since the early 2000s may represent dramatic improvement for fungal endocarditis: (i) a new class, the echinocandins, has the potential to improve the management of Candida endocarditis owing to its fungicidal effect on yeasts as well as tolerability of increased dosages; and (ii) improved survival in patients with invasive aspergillosis with voriconazole compared with amphotericin B, and this may apply to Aspergillus sp. endocarditis as well, although its prognosis remains dismal. These achievements may allow selected patients to be cured with prolonged medical treatment alone when surgery is considered too risky.

Résumé : La vulnérabilité croissante aux aléas extrêmes et les conséquences du changement climatique accentuent l’exposition des Antilles françaises aux risques naturels. Dans ce contexte, la Caisse Centrale de Réassurance par son rôle dans l’indemnisation des Catastrophes naturelles en France cherche à consolider ses connaissances sur les ouragans et les phénomènes induits comme les submersions, les inondations ou les glissements de terrain.À partir des archives antillaises et métropolitaines, une reconstruction de l’intensité des ouragans survenus depuis le début du xviie siècle a été possible. Elle permet ainsi d’évaluer l’exposition des territoires antillais. L’analyse des dommages a permis de proposer une évaluation des enjeux et ainsi saisir la construction de la vulnérabilité. Les réponses apportées en matière de gestion du risque depuis le xviie attestent de la volonté d’assurer la protection des enjeux et des populations et mettent en avant les relations entre risque et aménagement du territoire.
The rising vulnerability to Extreme hazard and the consequences of climate change increase the exposure of French Antilles to natural hazards. Therefore, the French reinsurance company Caisse Centrale de Réassurance aims to develop its scientific knowledge of hurricanes and induced phenomena like storm surges, floods and landslides.With the study of historical archives, located in the Antilles and Metropolitean France, it was possible to build an exhaustive hurricane Severity chronology since the 17th century. Then, a detailed damage analysis in specific strategic areas has offered the opportunity to assess the evolution of the vulnerability of the French Antilles societies. Furthermore, the Risk Management policies, since the 17th century, attest the willingness to protect strategic areas and populations and highlight the link between risk and land use.

Résumé : Cet article souligne la particularité des politiques locales menées récemment en Martinique et en Guadeloupe en matière de gestion du risque sismique. Ces Départements français des Amériques, fortement exposés à la menace sismique, s’impliquent depuis peu dans une véritable dynamique préventive soutenue par l’action des Collectivités. Des stratégies locales de réduction de la vulnérabilité humaine et technique sont expérimentées au bénéfice de la population. Elles viennent renforcer ou compléter les efforts étatiques visant une plus grande implication du citoyen à son information et à sa sécurité face aux séismes.
This article underlines the characteristic of the local policies followed recently in Martinique and Guadeloupe as regards seismic risk management. These French Departments of Americas, strongly exposed to the seismic threat, imply themselves recently in a true preventive dynamics supported by the action of the Communities. Local strategies of reduction of the human and technical vulnerability are tested for the benefit of the population. They come to reinforce or supplement the official efforts of French State aiming a greater implication of the citizen to his information and its safety against the earthquakes.

Résumé : International audience
Everyone is subject to environmental exposures from various sources, with negative health impacts (air, water and soil contamination, noise, etc.or with positive effects (e.g. green space). Studies considering such complex environmental settings in a global manner are rare. We propose to use statistical factor and cluster analyses to create a composite exposure index with a data-driven approach, in view to assess the environmental burden experienced by populations. We illustrate this approach in a large French metropolitan area. The study was carried out in the Great Lyon area (France, 1.2 M inhabitants) at the census Block Group (BG) scale. We used as environmental indicators ambient air NO2 annual concentrations, noise levels and proximity to green spaces, to industrial plants, to polluted sites and to road traffic. They were synthesized using Multiple Factor Analysis (MFA), a data-driven technique without a priori modeling, followed by a Hierarchical Clustering to create BG classes. The first components of the MFA explained, respectively, 30, 14, 11 and 9% of the total variance. Clustering in five classes group: (1) a particular type of large BGs without population; (2) BGs of green residential areas, with less negative exposures than average; (3) BGs of residential areas near midtown; (4) BGs close to industries; and (5) midtown urban BGs, with higher negative exposures than average and less green spaces. Other numbers of classes were tested in order to assess a variety of clustering. We present an approach using statistical factor and cluster analyses techniques, which seem overlooked to assess cumulative exposure in complex environmental settings. Although it cannot be applied directly for risk or health effect assessment, the resulting index can help to identify hot spots of cumulative exposure, to prioritize urban policies or to compare the environmental burden across study areas in an epidemiological framework.Journal of Exposure Science and Environmental Epidemiology advance online publication, 24 September 2014; doi:10.1038/jes.2014.66.
